早实薄皮核桃品种引种筛选试验及综合评价

近年来,随着核桃产业的发展和早实薄皮核桃的推广应用,青海省河湟谷地也纷纷引种。由于引种前缺乏相关研究,引进品种杂乱,其表现良莠不齐,优少劣多现象突出。为了筛选出能适于该地区栽培的薄皮核桃品种,对引进的9个早实薄皮核桃品种开展了引种试验和观测分析,采用数据直观分析和主成分分析相结合的方法,对各品种果实的经济学性状进行了分析评价,筛选出了辽宁1号、中林5号为适于青海省栽培的优良品种,这两个品种可在该区域适度发展。

Introduction and selection experiments and comprehensive evaluations of early-bearing and thin-shell walnut cultivars

With development of walnut industry and promotion of early-bearing and thin-shell walnut cuitivars in recent years,the cultivars had been introduced to the valley of Yellow River and Huangshui River of Qinghai.But due to lack of relevant researches before introduction,the introduced cultivars were mussy and uneven in quality,among which the low-quality cultivars obviously outnumbered the fine ones.In order to select some thin-shell walnut cultivars suitable to be planted in the region,the cultivars were observed and analyzed through introduction experiments,and economic characteristics of the cultivars were analyzed and evaluated by the means of combining visual data analysis and main component analysis.Liaoning No.1 and Zhonglin No.5 were selected as the fine cultivars suitable to be cultivated in Qinghai,and the two cultivars could be appropriately developed in the region.
